In the wake of an anti-censorship rally in Berkeley, California that saw over 20 arrested Saturday, sleuths have watched event videos and picked out an anarcho-communist college professor named Eric Clanton as their prime suspect in multiple murder attempts at the event. Clanton is listed on faculty in the philosophy department of Diablo Valley College. The evidence at this point is compelling and circumstantial.

Outraged accusers have vandalized the 28-year-old’s profile on RateMyProfessors.com, and at least one claims to have hacked Clanton’s Amazon.com profile and made purchases under his name.

One masked black bloc terrorist was photographed several times taking swings at attendees—at 15 seconds into this video striking the head of an unsuspecting man in a red shirt; at the two-minute mark in this video attacking a man with a blue helmet, and then another with a black shield; and at the 10-second mark in this video swinging at a green-helmeted man and later fracturing the military-style helmet of another. “Bike lock man” smacks others in this video from LiveLeak, and at 1:22 his mask comes off.

Analysis of photographs led readers of the 8chan and 4chan image boards to conclude that Clanton was the attacker, based on reviews of the academic’s fashion choices, facial structure, as well as his ideological leanings. Clanton’s Facebook and Twitter pages appear to have been deleted in the wake of his coming under suspicion. Early this morning, San Francisco State University deleted an alumnus page for Clanton, and tells Gotnews.com that “Eric Clanton is not an employee of the University.”

A syllabus on Clanton’s website, however, documents his role teaching at San Francisco State as recently as fall 2014, leading an “introduction to critical thinking” course, where his job was to help students reach “well-supported factual or judgmental conclusions.”

Clanton’s profile on a dating website names, among the “things I could never do without,” his bike, a “pen (Stolen zebras [brand pens] are my taste)” and “a sturdy pair of shoes.” The bike lock suspect was wearing very similar shoes as Clanton was on his dating profile, similar sunglasses, and had a pen, possibly from Zebra, in his back pocket.
